PRINTING-STRIP -MO'UNTING.

Application filed December 18, 1925. Serial No. 76,298.

This invention relates to a stamped sheet metal plate adapted to carry embossed printing strips. For instance, while not limited thereto, the plate may be a small rectangular member having means for holding afew parallel printing strips constituting an address, eachplate so equipped being adapted for use in an address machine.

My strip mounting is in the nature of an improvement on Patents Nos. 1,438,580, 1,438,584, 1,488,582 granted December 12, 1922, to my assignee, The American Multigraph Company, as assignee of Clifton Chisholm, William J. Demming and Burnie J. Craig respectively. Each of those patents shows plates having rows of raised projections and embossed printing strips resting on the projections and having inwardly flanged edges which underhang the projections. In the Chisholm patent, .the projections are independent and disconnected from each other, facing alternately inopposite directions; in the Deinming patent, raised but tons are provided, the opposite edges of each button acting as a pair of projections: In the Craig patent, corrugations are provided between the raised buttons, which, with the buttons, furnish a continuous type bed.

All of the prior constructions referred to are weak in certain regions. In the Chisholm and Demming plates there is nothing but the continuous plane of the plate between the projections. While in both the Demming and Craig plates thereare series of holes through the plate beneath the entire button area. These unreinforced portions of the plate or theholes, as the case may be, align in the direction from top to bottom of the plate, thus makingcontinuous unreinforced lines or zones, resulting in a plate which is likely to be bent in such transverse direction. j

It is the object of my invention to provide a plate which will have a continuous bed for supporting the embossed strip. and oppositely extending projections for holding it, and at the same time will be continuously reinforced from one end of the bed to the other, whereby there will be no weak regions along which the plate may be bent trans versely of the bed.

I accomplish the desired result by forming a continuous corrugation in the plate which may extend from a point near one end of it, to a point near the other end, and I extend the projections laterally in opposite directions from the top regions of these corrugations, while preserving the corrugation wall back of these projections. Thus,

whereverthere is a hole through the plate beneath a projection, there is also. immediately back of such hole, an upstanding portion of the platewhich reinforces it at that region. Thus a very stiflfplate is provicled. My invention is more fully described in connection with the drawings illustrating a preferred embodiment thereof and the essential novel features are summarized in the claims.

In the drawings Fig. 1 is a top plan of my improved printing strip mounting in the form of an address plate, other features of the plate, such asthe card carrier, etc, being omitted for simplicity of illustration; Fig. 2 is an end view of the plate on the same scale as Fig. 1; Fig. 3 is an enlarged cross section partly through projections facing in one direction and partly through projections facing inthe opposite direction, as indicated by the oil-set line 3 3 onFig. 1; Figs. 4 and 5 are cross-sections of portions of the plate at adjacent rows of buttons, as

indicated by the correspondingly numbered linesin Fig. 6; Fig. 6 is a perspective of a portion of the plate; Fig. 7 is a bottom plan of the plate.

When my invention is embodied in an ad dress plate, as shown in the drawings, such plate, designated 10, preferablyconsistsof a single piece of metal. If desired this may have its top and bottom edges curled over toward the front as shown at 11 and 12 and its end edges bent toward the rear in the form of hollow tubes as indicated at 13, thus stiffening the plate in these regions. EX-

tending along. the plate are a number of parallel upwardly extending corrugations 15, six of such corrugations being shown in Fig. 1. They extend from near one end of the plate to a corresponding distance from the other end and are comparatively close together asshown and are all alike in construction.

Each corrugation 15 has a succession of lips cut out principally or entirely from a side wall of the corrugation and turned upwardly into a plane parallel with the general plane of the plate. Every alternate lip is formed on the same side of the corrugation and extends toward the same edge of the plate, as for instance the lips 16, which project trom the corrugation toward the bottom edge of the plate. The intermediate lips 17 are formed in the same manner from the other side of the corrugation, turned upwardly from cut-out portions thereof, and extended parallel with the plane of the plate toward the top edge. The projections are very close together so that the contour of a double row of projections makessubstantially a sinuous line extending from one end of the raised bedto the opposite end.

It will be seen from the drawings that the corrugations are not unduly weakened by being cut-out to furnish material for the projections, because ineach case the opposite side of the corrugation and the top of the corrugation is maintained intact. There is no region across the rows which is unreinforced by the corrugations. At the same time a continuous support is provided from one end of the row to the other for the overlying embossed strip. p

In turther explanation of the increased strength of my plate, commentmay be made that the holes through the plate which provide the lips are not only small in area, but when measured in a direction normal to the plane of the plate are in fact narrow slits, resulting from the short curved cuts through the metal of the plate being almost entirely through the upstanding side wall of the corrugation. The short curved cuts being disposed alternately may provide the ne essary width for the engagement with the flanges ot the printing strips without. these cuts being individually as great as those of the plates of the patents referred to. The result is that in my platethe aggregate length of the cuts is less than the aggregate length of cuts of the plates of those pa-tents. It will be seen from an inspection 0'! Fig. 7 that thelength or thevcorrugation wall re tained behind any lip. as shown at 18. is materially greater than the longitudinal distance across the lip, thus making a very stable backing for thelip and resulting in the lips being effectively supported. Furthermore, the portion 18 of the corrugation wall retained on one side overlaps the retained portions on the opposite side so that, on the transverse line adjacent the edge of any lip, both walls of the corrugation are uncut.

The embossed strips are indicated in the drawing at 20. They carry upwardly projetting printing corrugations 21 and. their edges are flanged inwardly at 22 to underhang the projecting lips as shown clearly in Fig. 3. These strips may readily be shoved into place each on a row of projections, and

when so mounted may be in proper position to constitute an address, as illustrated in Fig. 1.

I claim:

1. A printing strip mounting comprising a plate having a continuous corrugation and a succession of lips, eachprojccting to one side or the corrugation while the opposite wall of the corrugation is continuous behind the lips.

2. A printing strip mounting comprising a plate having a continuous corrugation and a succession oi lips alternately cut from the plate material at opposite sides of the corrugation and turned upwardly therefrom, the corrugation wall being continuous behindthe root of the lip.

3. A printing strip mounting comprising a plate having parallel upwardly stamped corrugations and lips. cutout principally from the side walls of the corrugations and turned upwardly, the successive lips being on alternate sides and the corrugation being intact on the side directly opposite the lip.

4. A printing strip mounting comprising a sheet metal plate having stamped upwardly therein a plurality of parallel corrugations and having lips formed from the side wall of each corrugation, said lips extending first in one direction and then in the other, the corrugation being intact across the base or each lip and the lips being all in the same plane parallel with the general plane of the plate.

5. A printing strip holder comprising a single sheet of metal having stamped up therefrom, parallel corrugations extending from aregion near one endrof the plate to a region near the opposite .end, one side wall or each corrugation being cut out at inten mittent regions to provide lips which are turned upwardly from such wall and are anchored tothe opposite wall of thecorrugation. the lips being first on one side and then on the other while the wallet the corrugation opposite the lip is maintained.

6. A printing strip holder comprisinga plate carrying a row of projections extending alternately first in one'direction only then in the opposite direction only transversely of the line of the row. each projection substantially joining the adjacent projection whereby the contour presents a sinuous line. i r

7. The combination of a plate having, a. stamped up corrugation with lipsprojecting first in one direction only then in the opposite direction only from the top region of the corrugation and anchored by the wall of the corrugation at thehase of the lip and a.

8. The combination of a plate having stamped up thereon a plurality of'continuous corrugations parallel with each other, each corrugation having lips exiten'ding from its top region transversely of the corrugation, the lips extending first in one direction and then in the opposite direction and the corrugation being complete behind the base of the lip and an embossed printing strip overlying the respective corrugations and having flanged edges extending beneath the lips.

9. An address plate of the character described comprising a sheet metal member having stamped up therefrom, parallel corrugations, each corrugation extending from a region near one end of the plate and a region near the opposite end, lips cut out of the side walls of the corrugations and turned upwardly therefrom into a plane parallel with the plane of the plate body, the lips extending first in one direction and then in the other direction and the side Wall of the corrugation being intact immediately behind the lip, each lip closely joining the adjacent lip, and a series of embossed printing strips overlying the corrugations and having inwardly flanged edges projecting beneath said lips.
